This summer, the Web site version of the weekly (pubs.acs.org/cen) started publishing movie reviews that focus (although not exclusively) on the accuracy of the science, especially the chemistry, in the latest releases.

Q : What is "in the latest releases"? the science or starting publishing movie reviews? That is, Does " in the latest releases" modify "the science" or "started publishing..."? I think it specifies "started publishing....". What do you think?
